This insert measures 1-3\/8 inches in diameter and features a 130-degree point angle optimized for drilling into steel, cast iron, and non-ferrous metals. Manufactured from high speed steel (HSS) with a physical vapor deposition (PVD) titanium nitride (TiN) coating, the 1021T-0112 delivers improved surface hardness and wear resistance compared to uncoated HSS inserts. The insert height is 7\/8 inches with a thickness of 0.1875 inches. It is sized to fit Series A seat holders. Machinists and tool-and-die professionals are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThe 1021T-0112 is suited for production and job-shop drilling operations where spade-style tooling is preferred for deep-hole or large-diameter drilling. Its TiN-coated HSS construction makes it appropriate for cutting steel and cast iron workpieces, as well as non-ferrous metals. The Series A seat size aligns it with Allied Machine and Engineering Series A spade drill holders commonly used on CNC machining centers, drill presses, and manual lathes. The 130-degree point angle helps reduce thrust force and center the drill on entry, which is useful in applications requiring consistent hole location.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8 inch diameter for large-bore drilling applications\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle reduces entry thrust and improves drill centering\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating applied via PVD process for added surface hardness and extended tool life\u003c\/li\u003e\n  \u003cli\u003eSeries A seat size for compatibility with standard Allied Machine Series A spade drill holders\u003c\/li\u003e\n  \u003cli\u003eSuitable for steel, cast iron, and non-ferrous metal workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit Series A seat spade drill holders.

Ensure the machine spindle is fully de-energized and locked out before changing inserts. Inspect the seat pocket for chips or wear before installation, as debris in the seat can cause insert movement and poor hole quality. Follow applicable machine shop safety practices and consult the holder manufacturer's documentation for proper insert orientation and clamping torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size \/ Series\u003c\/strong\u003e: A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD (Physical Vapor Deposition)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1021T-0112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51750545686834,"sku":"1021T-0112","price":87.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1b656720df1697cfe55530662ec25dd.jpg?v=1788916483","url":"https:\/\/voomisupply.com\/products\/allied-machine-1021t-0112-spade-drill-insert-1-3-8-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
